PNEUIVIAIIC FLOOR-OILER.

Specicaton of Letters Patent.

Patented Mar. 5, 1912.

Application filed May 18, 1910. Serial No. 561,984.

To all 'wh-omit may concern: A

Be it known that I, CHARLES W. Comer, a. citizen of Canada, residingat'Malden, in the county of Middlesex and Commonwealth of Massachusetts,have invented certain new and useful Improvements in PneumaticFloor-Oilers, of which the following is a specification.

The object of this invention is t-he construction of an improvedhand-operated means for spraying floors with oil, for spraying shrubsand plants with insect-desiroying fluids, and for other purposes of alike character.

Referring to the drawings forming part of this specication, Figure 1 isan elevation of the device in its normal position for spraying floors.Fig. 2 is a sectional elevation of the upper part ofthe container, andthe lower part of the air-pressure pump. Fig. 3 is a sectional elevationof the lower part. of said container and of the sprayernozzle. Fig. 4:is a sectional view of said iozzle. Fig. 5 is a side view of thevalveoperating lever. Fig. 6 is a cross section of said nozzle. Fig. 7is a perspective view of the upper part of the handle or ring andconnections, used in operating said valve.

The container is preferably of sheet metal, with a cylindrical body 2and conical ends 8. Within this is put the oil or other liquid to besprayed, the same being poured in through the funnel mouth 4 after thepump 5 has been unscrewed therefrom. See Fig. 2. Connected with the apexof the lower end 3 is the spraying nozzle and valve controlling thesame; the valve consisting of the slightly tapered ,plug 7 rotatablyheld in the nozzle 9, as shown in Fig. 4; the plug having a recess 10adapted to communicate with the stem 11 leading from the container, andalso a small hole 12 adapted to coact with the slot 18 in the nozzle, asshown in Figs. l and 6.

lVhen a sufficient air pressure is maintained upon the surface of theliquid in the container, and the plug 7 is turned to present said recessto said stem and said hole to the edge of said slot, as in Fig. 6, thensaid liquid will be emitted in a thin but wide spray extending to aconsiderable width. 'Io maintain such air pressure, the pump cylinder 5is provided with a plunger 15 of the usual bicycle-pump type, operatedby the stem or rod 16 and handle 17. Said cylinder terminates in athreaded end 19 adapted to be screwed into air-tight engagement with thecorrespondingly threaded socket 20 fixedin the mouth or throat of thecontainer. Through said terminal is a port 21 normally closed by a ball22 and spring 23 pressing the latter into its seat. working the plungera few times, a sufficient air pressure is maintained upon the surface ofthe fluid in the container to force the fluid out through the valve(when opened) and to cause the same to issue in the form of spray asabove described.

The sprayer is adapted for throwing disinfectants and other liquids uponfloors, walls and ceilings, in the following manner: As is evident, whenthe spraying nozzle opens from the lowermost point of the container, andthe liquid is thereby between such outlet and the body of air undercompression, the device as above described will work according to plan;but if the container has its nozzle elevated to spray upon a ce1 y ingor upper part of a wall, the body of an' under compression will risebetween the liquid and the nozzle, and air alone will escape. To remedythis, a tube 25 is connected with the outlet to the nozzle, within thecontainer, as shown in Fig. 3, having a freely swinging terminal 26.This terminal or branch may be of soft rubber, and its length and thatof the tube 25 such that whenthe sprayer is held in the positionillustrated by Fig. 1, the free end of said rubber branch will hang downclose to the bot-tom of the container and so make sure that the liquidalone will be forced` out. If the' container is held horizontally, saidbranch will gravitate to the lowermost side thereof, and still be out ofthe reach of the body of air above the liquid; or if the container beelevated to present the spray to the ceiling of a room, or to some tallshrub or vine, the flexible branch will again descend to keep its mouthbelow the liquid. In this manner, the sprayer can be moved in anydirection or to remain automatically operative.

In holding the container, the user grasp it about itsneck between thefunnelmouth and top end 3; in this position the pump lying against hisarm and thereby aiding him in directing its discharge. While his hand isthus holding the container, his foreinger is hooked into the ring 30which is connected by a tape 31 to the lever 32 rigid with the plug 7. Acoiled any angle, and always should Vso spring 33 encircling the neck ofsaid plug normally closes the latter, so that pulling upon said tapeopens the valve, and its release permits t-he valve to close. A finger34 projecting from said lever into engagement with a stop-screw 35,limits the opening of the valve to the exact point required for theproduction of a perfect spray. See Figs. 4 and 5. The upper part of thetape is retained in position, and at the same time permit-ted freevertical movement, by means of the wire link 36 pivot-ally attached tothe conical top of the container and also to the tape, as in Fig. 7.This link is formed with an elbow-bend in order to rest against the saidtop and normally support the tape and ring in the position illustrated.For better security against injury in transportation, this tape is maderemovable from said link and also from the lever 82, by means of theshepherds-crook bend 37 which connects it with the link, and by thenarrow slit 39 opening from the hole 40 in said lever, into which thetape-ring 41 is caught. Sometimes the ball valve 22 fails to perfectlyclose the port to the container, and the air will slowly leak from thelatter into the pump cylinder and thereby cause the plunger to graduallyrise to its upper limit. This brings the plunger handle into the way ofthe user. To stop the same I provide the plunger rod with a spur 42,which is more or less helical with respect thereto, adapted to be caughtin the hole 43 in the cylinder top 44, and so hold the plunger in itsinnermost position.

Inasmuch as one of the most important uses of this sprayer is for thepurpose of oiling floors, and oil is very injurious in its effects uponrubber, it is best to make the flexible tube or branch 26 of some othermaterial than that above referred to. I therefore prefer to make saidbranch of soft leather, having a helix 27 of fine Wire Within it forcausing it to maintain its shape. The extremity of this branch is asection of metal tubing 28 in add to the weight thereat that there canbe no failure of its gravitating constantly to t-he lowermost part ofthe container.

l/Vhat I claim as my invention and for which I desire Letters Patent isas follows, to wit l. A sprayer comprising a container having a sprayingnozzle atits lower end, a tapered top, a funnel rising from the smallend of said tapered top, a pressure-pump rising from the containerwithin said funnel, a spring for closing said sprayer nozzle, and a linkbetween said sprayer nozzle and said top, whereby the hand of t-he userclasped about said funnel and top and thereby supporting the sprayer canoperate the sprayer nozzle at will.

2. A sprayer comprising a container having a sprayer nozzle at its lowerend, a hand-engaging means at its top, a tape operatively connected tosaid nozzle and having a finger-engaging ring at its upper end, and alink pivoted both to said tape and to the top of the container, thepivotal point of said link to said top being higher than the connectingpoint of the link and tape, and the link being disposed to bring thetape substantially into contact with the periphery of the container whenthe sprayer nozzle is closed, whereby, when the tape is drawn upward toopen said nozzle, the tape moves out of contact with said periphery.

In testimony that I claim the foregoing invention, I have hereunto setmy hand this 16th day of May, 1910.
